Abstract

CENTRÍFUGA. A presente invenção se refere a centrífugas uteis para, entre outras coisas, remover glóbulos vermelhos do sangue total, e reter plaquetas e outros fatores em um volume reduzido de plasma. A plaqueta rica em plasma (PRP) e ou plaqueta pobre em plasma (PPP) pode ser obtida rapidamente e está pronta para injeção imediata no hospedeiro. Representações podem incluir válvulas, operadas manualmente ou automaticamente, para abrir portas que descarregam o excesso de glóbulos vermelhos e o excesso de plasma em recipientes separados retendo ao mesmo tempo as plaquetas e outros fatores na câmara centrifuga. Altas velocidades utilizadas permitem que representações simples e pequenas sejam usadas ao lado do paciente durante procedimentos cirúrgicos. As representações também podem ser usadas para a separação de líquidos ou chorume em outros campos como, por exemplo, a separação de pigmentos ou lubrificantes.CENTRIFUGE. The present invention relates to centrifuges useful for, among other things, removing red blood cells from whole blood, and retaining platelets and other factors in a reduced volume of plasma. Platelet-rich plasma (PRP) and or platelet-poor plasma (PPP) can be obtained quickly and is ready for immediate injection into the host. Depictions may include valves, manually or automatically operated, to open ports that discharge excess red blood cells and excess plasma into separate containers while retaining platelets and other factors in the centrifuge chamber. High speeds used allow simple and small representations to be used at the patient's side during surgical procedures. The representations can also be used for the separation of liquids or slurry in other fields, for example, the separation of pigments or lubricants.
